Hello. I have a problem. I need to get std::locale object for my locale (ru_RU.UTF-8) on a systems that don't have one. I decided to take a look at boost::locale::generator, as it has ICU as a backend and there must be full locale info in it. But to my surprise generator do not generate only locale facet that I really need - ctype one. For example following code will go "oops" branch: #include <iostream> #include <boost/locale.hpp> #include <boost/locale/localization_backend.hpp> using namespace std; int main() { using namespace boost::locale; localization_backend_manager my = localization_backend_manager::global(); my.select("icu"); // I know that icu is default backend but I select it explicitly to be sure. boost::locale::generator gen(my); std::locale loc( gen.generate( "ru_RU.UTF-8" ) ); if( !std::isalpha( L'ф', loc ) ) std::cout<< "Oops\n"; else std::cout << "Ok\n"; return 0; } But if I will do std::locale loc( gen.generate( std::locale( "en_US.UTF-8" ), "ru_RU.UTF-8" ) ); It will work, as it will have ctype facet from en_US.UTF-8 locale, but that is not a solution as I may not have en_US.UTF-8 locale either, and on some systems, (for example iOS) I won't have any UTF-8 locale available for std::locale constructor. So I'm curious, why generator won't generate ctype locale? Is there any reason behind it? Or maybe I'm doing something wrong? Is there any way to generate locale with proper ctype facet from ICU using boost::locale::generator? -- -- With respect Gleb "Crazy Sage" Igumnov mailto:crazy.sage@gmail.com
